` burner.

Other gas flows into the bore 2l, thence to the passageways 6 and I2 to the small jet. The valve member terminates short of the end of the chamber 4, thus providing a gas flow space 33 which connects the bore 2I and outlet passageway 6. Now it will be noted that as the leading edge of the slot 22 begins to open with the inlet passageway 3 that the gas flow to both jets is opened simultaneously, and the opening increases until a position is assumed as substantially shown in Fig. 4. At this time there will be a high flame at the The valve may be further adjusted by turning the valve member further clockwise toa position substantially as illustrated in Fig. 5. Here it will be noted that the valve member has a closed off passageway 5. However, all the while until the extreme position has been reached, as shown in Fig. 5, the passageway 3 is open wide to the bore 2l so that there is a full charge of gas to the small jet. At this time a small or simmering ame may be present at the burner. When the valve is turned off gas continuously is supplied to the small jet through the range of movement of the valve member. Of course, in

' the reverse motion of the valve member gas is supplied to the large jet and ultimately the gas supply of both jets is cut off simultaneously.

When the valve is moved from off position the pin of the valve member moves until it strikes the quick lift cam face 3|. This serves as a substantial stopping agency to the movement of the valve, and at this time the valve is substantially fully opened, as shown in Fig. 4f Additional pressure on the valve member will Cause the pin to shift past the washer by shifting the same against the action of the spring 29. Thus the valve is adjusted to simmering position. When it is desired to turn off the valve lthe pin moves easily past the washemby reason of the slow lift cam face 2I. Thus ifu desired the valve may be operated to and from closed and fully opened position, utilizing the intermediate spring pressed stop member. Additional pressure is needed to get the pin past the quick lift cam face to adjust the valve to a low flame or simmering condition. Y In the modified form shown in Figs. 8 9, and 10, the valve body and jet arrangement and its passageways may be identical with the body heretofore described. The rotary valve member may be identical in general construction, but the arrangement and location and function of the ports are different. The reference characters on the valve body and its passageways and the rotary valve member are the same, save for the circumferential slot and axial bore in the valvemember. In this structure one jet, as for example, the small jet I6, connects into the outlet passageway I2 and the large jet into the passageway II. The rotary valve member has a bore 22a. and a slot 2Ia. In closed position the parts are substantially as shown in Fig. 8 with the valve closing off the inlet passageway 3. When the valve is turned on, as illustrated in Fig. 9, the gas is first opened to the small jet, through the slot 2Ia. and borel22a to the outlet I2. It is at this position that the pin 25 will meet the stop member 28. As additional force is applied the valve may be turned from the Fig. 9 position to Fig. l0. In this position the small `iet is opened as will readily be appreciated, and the large jet is now open by reason of the gas iiow from the passageway 3 through the circumferentialslot 2| a into passageway 5 and then into outlet passageway I0. As the valve is turned off the large jet is first shut off and then finally the small jet is closed. In this form the valve member is rotated counterclockwise as the valve is turned on, and clockwise as the valve is turned lo' In the preceding form the valve member is rotated clockwise as it is turned on and counterclockwise as it is turned off". However, this is an optional arrangement, as the valve may be made to turn in either direction when turning non or non.

It is to be particularly noted that the valve member is of a simple formation and yet this desired action is obtained in a double jet valve. The slot and bore are of generous proportions as are the bores and passageways in the valve body. There are no small apertures or passageways 1iable to get clogged within the valve body. The flow of gas is controlled by the small jet rather than by the employment of small apertures or passageways in one or both of the valve members.
